Product Specifications

Key Features

• 280mAh High-Efficiency Capacity — Optimized energy output for slim-profile devices, delivering extended operating time for GPS tracking sessions, continuous health monitoring, and IoT data transmission cycles without the need for frequent recharging
• Ultra-Narrow 14mm Width — The exceptionally slim 14mm body makes the 451447 ideal for wristband wearables, pen-shaped GPS trackers, slender IoT modules, and any device where internal width is the primary design constraint
• Stable 3.7V Flat Discharge Curve — Consistent voltage output throughout the full discharge cycle ensures reliable sensor readings, stable GPS signal transmission, and uninterrupted device operation from full charge to cutoff
• Built-In Multi-Protection Circuit (PCM) — Integrated protection against overcharge, over-discharge, over-current, and short-circuit conditions, safeguarding sensitive medical and IoT electronics from battery-related damage
• Medical-Grade Reliability — Tight capacity tolerance and consistent cell-to-cell performance make the 451447 a dependable choice for personal emergency devices, health monitors, and other applications where power consistency is safety-critical
• Excellent Low-Temperature Performance — Maintains effective discharge capacity down to -20°C, ensuring reliable GPS tracking and IoT sensor operation in outdoor, cold-chain, and industrial field environments
• Long 500+ Cycle Life — Engineered for longevity, supporting years of daily charge/discharge use before meaningful capacity degradation, reducing device maintenance and battery replacement frequency
• Low Self-Discharge Rate — Retains stored capacity effectively during periods of device inactivity, keeping standby devices and backup trackers ready for immediate deployment
• Lightweight Soft-Pack Construction — Flexible polymer pouch design is lighter than equivalent cylindrical cells and molds cleanly to flat-panel device interiors for seamless mechanical integration
